About This Site

What This Site Is

BusinessDayRules.com is a static informational reference site that explains how US business day rules work — including federal holidays, bank cutoff times, ACH processing timing, and weekend payment delays. The articles here cover the rules and concepts behind business day calculations and payment processing.

What This Site Does Not Do

This site does not provide legal, financial, or banking advice. It does not make bank-specific claims about cutoff times or processing schedules. It does not guarantee payment timing for any specific transaction.

The Relationship Between This Site and Calculators

The articles on this site explain the rules. The calculator tools linked from each article let you apply those rules to specific dates and situations:

• BizDayChecker.com — check whether a date is a business day and count business days between dates
• BankCutoffChecker.com — check bank cutoff times and payment posting
• PayrollDateChecker.com — find actual payday dates accounting for weekends and holidays
